net: mvneta: Add support for 2500Mbps SGMII
The mvneta controller can handle speeds up to 2500Mbps on the SGMII interface. This relies on serdes configuration, the lane must be configured at 3.125Gbps and we can't use in-band autoneg at that speed. The main issue when supporting that speed on this particular controller is that the link partner can send ethernet frames with a shortened preamble, which if not explicitly enabled in the controller will cause unexpected behaviours. This was tested on Armada 385, with the comphy configuration done in bootloader. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
